#Typer

Typer is an Angular directive that simulates someone typing and deleting over a list of words. The directive is highly customisable and allows the words to be set by passing an array of strings as an attribute, the transition times can be set on the directive aswell as callback functions to get invoked after each action ('Type', 'Delete', 'Highlight')

Declaring directive

Then declare the typer directive in your HTML

<typer words="['JavaScript', 'Angular', 'Cats']" type-time='150' backspace-time='200' start-delay='1500' highlight-background='#2980b9'></typer>

Note: The directive will inherit the styles of its parent element so it is recommended to nest it like below

 <h1 class="main-title">I love <typer words="['JavaScript', 'Angular', 'Cats']" type-time='150' backspace-time='200' start-delay='1500' highlight-background='#2980b9'></typer></h1>
